Fe-based　coatings　with　CaF2　were　deposited　on　aluminum　alloy　substrate　by　arc　spraying　using　spray　materials　of　Fe-Cr-B-C　alloy　cored　wire　added　to　an　amount　of　CaF2.　The　effect　of　CaF2　content　on　microstructure　and　wear　performance　of　the　coatings　was　examined　by　scanning　electron　microscopy　(SEM),　X-ray　diffraction　(XRD)　and　high　temperature　frictional　wear　test.　The　results　show　that　the　CaF2　layer　formed　distributed　in　the　arc　spray　coatings.　When　the　CaF2　content　increased　from　0%　to　10%,　the　friction　coefficient　and　wear　mass　loss　of　the　coatings　is　reduced,　and　surface　of　the　Fe-based　coatings　with　CaF2　is　smooth　after　wear　test.
